Question
Chapter 6, Problem 1DQ
To determine
Measurement of elasticity of demand.
Expert Solution & Answer
Explanation of Solution
Elasticity is the degree of responsiveness from the part of the consumer toward the changes in the
Elasticity is measured with the percentage change in the quantity demanded divided with the percentage change in the price in the economy. The calculation is made in percentage terms in order to bring uniformity between the price and the quantities. This is because the price and quantity will be measured in separate measures and cannot be directly used to calculate elasticity. When the percentage term is used to measure elasticity, the units of measurement do not matter the elasticity measurement. It is the reason behind the use of the percentages while calculating elasticity.
Economics Concept Introduction
Elasticity: Elasticity is the degree of responsiveness from the part of the consumer toward the changes in the price level in the economy.

3. Consider the following estimated regression equation, estimated using a sample of firms, where RDis total firm spending on research and development in USD ($), Revenue is total firm revenuein USD ($), and W ages is the firms’ total spending on wages in USD ($) (standard errors inparentheses):RDd = 1000(600)+ 0.5(0.1)Revenue + 1.5(0.5)W ages,(a) Interpret the coefficients on each of the explanatory variables. (b) Which of the three coefficients are statistically significant at the 5% level of significance? Howdo you know?
